WILLIAM W. SCOTT, OF PLANTCITY, FLORIDA.

- IIORN-BLOWING-ATTACHMENT FOR AUTOMOBILES.

Be it known that l, WILLIAM TW. SCOTT,

""a citizen of the United Sta-tes, residing at Plant City, in the county of Hillsboro and f State of Florida, have invented certain new and useful improvements in Horrrlowing p Attachments for Automobiles; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the i art to which it appertains to make and use fthe same. i

This invention relates to new and useful improvements in automatic signaling devices and has particular reference to devices of such character as are adapted to be attached to the axle of an automobile and to sound the horn 'when the automobile is rounding i' a curve.

As a particular object this invention contemplates the provision of an appliance of y the above described character which shall be K readily attached to or detached from the axle of a vehicle and which will instantaneously and automatically sound the horn when the machine is rounding a curve.

i A furtherobject is the provision of a device which will permit of. slight movements 'from a straight path of travel as often becomes necessary in avoiding stones, ruts, etc.,

without necessarily sounding the alarm.

An object of equal .importance with the foregoing is to provide an automatic signal- 'ing' device of the type described which is constructedwith such regard to proper number and arrangement of parts as to be cheaply manufactured, will be durabl and bodied by such means'as are illustrated in "appended hereto to form plication.

effi-cient in operation and may readily bef applied to the axle of any automobile with a minimum expenditure oftime and labor and without requiring any alteration in tile-conistruction of the latter.

` The above and additional objects are emthe accompanying drawings, described` in the followingspecication and more particularly pointed out in the claims which are a part of this ap# BeforeV taking up the description of the drawing, I desire to emphasize the fact that 'while my invention has been designed as a particular reference tothe needs of automobileshas been illstrated and" willY here-- Speecation of Letters Patent.

Application led J une 3, 1914. Serial o. 842,553.

y-inafter be described in that connection, it

may, nevertheless, be applied with equal efficiency to a street railway car or any other type of moving vehicle.

In reference to the drawings wherein I' have described the preferred embodiment of my invention as it is reduced to practice and throughout the several views of which like characters of reference designate similar parts, Figure 1 is a top plan View of the forward axle of an automobile showing my device applied thereto. Fig. 2 is a longitudinal section through a portion of the mechanism of my invention, and Fig. 3 is aplane indicated ber 10 is arcuately curved as shown at 11` and is adapted to receive a similarly curved tube 12, which is held in place therein by means of bolts 13 and which extends toward the wheels of the vehicle in both directions l from the frame 9 and is externally screw threadedfor a short distance upon each of its extremities. The internally screw threaded sleeve l5 which is provided with the inner partition 16 connects this tube 12 with a similar tube 17 which however, is much shorter in length. Both extremities of these tubes 17 are externally screw threaded and the outerends are closed with the apertured sleeve caps 18. The partition -16 of the sleeve 15 is apertured in itscenter as shown at 19 to form a bearing for the piston 2OA which is slidably positionedwithin the tube 17 and extends through the aperture 21 of the sleeve cap 18. The outer end of this piston 20 is bifurcated as shown at 21', the ends of the bifurcationl being journaled to receive the small rotatable wheel 22 which extends in spaced relation from the large .wheel 6 of the automobile.

A collar` 23 is fixed to the piston 2Q and adapted to slide uponV the inside of the'tube -17. The expansive spring 24 is also positioned within the tube 17 and encircles the piston 20 in such' manner as to bear against the ixed collar 23 at one extremity and against the inner partition 16 of the sleeve 15 on the other extremity. It will thus be seen that this spring 24: tends to force the ixedcollar 23 outwardly against the sleeve cap 18 and accordingly normally holds the piston 20 in 'the position shown in Fig. 2. The inward end of the piston 20 carries the downwardly extending lug 25 which works in a suitable slot 26 formed in the lower wall of the tube 12.

A lat elongated lever spring 27 extends throughout the length of the tube 12 and is so positioned underneath; said tube as to pass, directly under the slot 26 in which the lug`25 is adapted to move. In the normal position of the device as shown in F ig. 2 this spring 27, which is bent as shown at 28 adjacent its outward extremity, avoids contact with the lug 25, but is adapted to be actuated in other normal positions of the piston 2O in a manner to be hereinafter more fully described. A sleeve 29 is carried by the tube 12 in such manner as to encircle the leaf spring 27 and carries in its lower p0rtion the elongated contacts .30 which are suitably connected by means of the wire 81 to the electric horn of the automobile and which are normally kept from contact with the spring 27.

The operation of the spring 27 of my invention is very simple and entirely automatic as will be seen by a glance at Fig. 1. When the machine is so directed as to make a curve, deviating from a previous straight path of travel, one of the wheels 6, in swinging inwardly; will contact with the rotatable Wheel 22 and will force the piston 20 inwardly against thel action of the expanding spring 24. This inward movement of thel piston 20 will force the lug 25 against the leaf spring 27 which will in turn be accordingly displaced outward from the tube 1 2 and into Contact with the electrical connections 30 which will complete a circuit and cause the horn to sound continuously until the device is automatically released by the machine assuming a path of travel, such as will bring the wheel 6 once more at right anglesl to the axle 5. lWhen this takes place it will J"be evident that the piston 20 will be forced back to its normal position as before described by the spring 24 and the pressure of the lug 25, being removed from the leaf spring 27, will enable that spring to once more assume the position shown in Fig. 2 and accordingly break the connection with 'the electrical contacts 30 and thus cease the sounding ci: the horn.

It will be obvious in this connection that may desire to employ anattachment of obvious construction, which will enable the horn to be sounded on' the straightaway, either by placing the spring 27 against the contacts 30 by some other means than the piston 20, or else by separate appliances altogether. The provision of such an attachment however, will not in any way cilect the use or operation oi this invention.

Vhile in the foregoing l have illustrated in the drawings and described in the speciicaticn such combination and arrangement of elements as constitute the preferred embodiment of my invention, if desire to emphasize the fact that may malte such minor changes in the matter or' proportion and degree in later adaptations oli my device, as shall not alter the spirit of my invention as defined in the appended claims.
